all synthetic oils manufactors the same?

[boonie]

mobil.quaker state, havoline,castrol, red line etc... do all these synthetic oil manufactors produce a product that equal to each other? none really being superior when being compared to the rest? in other words will my 94 C4 work as well with mobile1 as it will with castrol syn-tech or red line?
thanks boonie

They are not equal to each other.

Mobil 1, AmSoil, Royal Purple, and Redline are the ONLY ones you should put in.

You should really stick with Mobil, because you can find it anywhere, the others you may have to order or look around for.

Wal Mart sells the big 5 quart bottles of synthetic for ~$18. Much cheaper than paying the $5.00+ per quart.
